✦ Synopsis

Hydrogenation

of naphthalene to tetralin using activated red mud as catalyst was studied as a typical hydrogen-donor system. Under the chosen reaction conditions, unprocessed red mud resulted in a conversion of naphthalene of 3.55%. The most active catalyst, prepared by adding 20 wt% of TiO, to the red mud, followed by acid digestion and re-precipitation, resulted in a 58% conversion of naphthalene. This technology may have an important bearing on processes such as coal hydrogenation or crude-oilresidue processing, where the rate of reaction and product quality may depend upon the rate at which a hydrogen-donor solvent can be rehydrogenated.
